Abstract

This paper takes the already known hybrid force-position control, and use it for a hybrid control manipulator with four degrees of freedom, from which 3 rotational and one translational. Control system used, use direct kinematics for finding the current position of the end-effector, and calculates the positioning error using the transposed Jacobian matrix. To observe the effectiveness of the control loops and controllers was modeled using Matlab Simulink, the proposed control system. Based on the obtained graphs and presented in this paper, the control system was tested in a virtual environment, where there are no risks of damage or injury to personnel. Using this test mode, one can achieve better control methods with varied performances, before moving to hardware implementation.
